Boost your endurance and oxygen capacity for a full 5 hours with this unique performance booster.

The science behind Nitric Oxide being a major performance booster is clear. By boosting Nitric Oxide you dilate your arteries and can increase your blood flow to working muscles, resulting in increased endurance and easier recovery.  That's why supplements like Sur Alt Red, BeetElite, and others have become so popular with endurance athletes.

The problem is that most Nitric Oxide supplements use L. Arginine to do this. While this gives you a short spike in Nitric Acid 3 hours after ingestion, the effect fades very quickly.

SwissRX has figured out (through clinical trials) that if you use L. Citrulline, it will signal your body to create L. Arginine (versus supplementing it). This creates the same peak level of Nitric Oxide, but you get to maximum levels after only 2 hours and the level is maintained for a full 5 hours with no decline.

SwissRX has combined L. Citrulline with a patented form of Grape Seed Extract that has been shown to activate your body's production of Nitric Oxide (via eNOS) and help maintain arterial dilation. 

Bottom line: Swiss RX has the most effective Nitric Oxide booster we've found on the market. It will open your blood vessels and increase oxygen flow, allowing you to go faster and harder for longer.

How We Use It

We use 4 capsules 1 to 2 hours before training.

The Swiss RX Story

We set out to find a supplement company we could trust for the world's top endurance athletes. A company that had the same obsession with quality and performance as our athletes do. After all, why spend millions of dollars optimizing the performance of a Tour de France champion only to give him a low-quality supplement with inferior or ineffective ingredients?

Our quest led us to SwissRX. SwissRX takes a "spare-no-expense" approach to procuring the highest quality Pharmaceutical Grade Ingredients. Only 3% of supplement companies go through the rigorous testing required for pharmaceutical grade labeling. But Swiss RX takes it even another step further. Whenever possible, they use the exact same ingredients used in medical studies but are often too expensive for supplement companies to use.  What we love about SwissRX is that our athletes can rest assured they are getting the identical ingredients that were proven to be effective in these studies.

Simply stated, SwissRX products work better because they contain better ingredients.

The SwissRX Guarantee

We know SwissRX is expensive, but you get what you pay for- especially when it comes to supplements. Other brands may be cheaper, but so are the quality of their ingredients. If you're anything like me, you'd rather pay a premium and KNOW you're getting the highest quality and most effective product possible 

That said, you can try it RISK-Free.  We are 100% confident SwissRX is the best supplement in the world, which is why guarantee it. If for any reason at all you are not THRILLED with your results after using this product for three weeks, contact us within 60 days of your purchase and a no-hassle MONEY BACK refund in the form of Feed Credit. There also is no need to return the product to us, just send us a picture.

Great quality, no holes or fading!
Size: Medium, Color: Black/Assorted
I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!

Well made and perform well, a little constricting
Size: Medium, Color: Black Assortment (6-pairs)
These socks definitely keep most of the moisture away from my feet, even in wet conditions, which is why I bought them. I am diabetic, though, and the recommendation is to wear socks that don't constrict at any point. These have a tight band around the opening that while it is not uncomfortable on, leaves a mark when I take them off. So far it's been ok, but if you have any kind of swelling in your feet or ankles these would probably not be the best. My foot measures size 8 and I wear size 9 Brooks running shoes. The socks fit me just right but based on the size of the opening and the overall length, I wouldn't think they would fit anyone more than a size larger. Overall well made and perform well as you would expect from this brand.
